Air Suspension is a type of automotive suspension that uses air
springs instead of conventional steel springs. Computer-operated
vents on the air springs, suspension sensors, and an onboard air
compress allow the system to maintain ride height and vary the
suspension's ride charateriatics.

Air ShockAn air shock is a type of overlade shock absorber that can be
inflated with air to increase the suspension’s load carrying
ability.

Shock absorbers and how they work

The shock absorbers reduce and slow down the vibrations from the
springs, which is why technically they are correctly referred to as
vibration dampers. Vibration dampers convert kinetic energy into
thermal energy through fluid friction. This involves the flow of
oil being slowed down by the valve passages inside the damper.

Advantages of Air Suspension Shock Absorber

1. Improve driving dynamics, road handling and comfortDriving dynamics, road handling and comfort are improved. The
suspension is soft and comfortable during slow driving and becomes
noticeably stiffer during faster driving. The suspension responds
to dynamic load as it reacts to live load.

2. Ideal axle heightThe car can be kept on its ideal axle height independent of its
variable load. Driving safety is improved due to better road
handling, for example, at night keeping the same headlight
position.
